The supplied attribute templates are in the symbol library folders and all attribute template drawing names begin with “AT_”. There are different attribute templates for different types of symbols and for different family codes. Attribute template drawings are AutoCAD drawings with AutoCAD Electrical toolset attributes. Symbol builder uses attribute templates to facilitate adding these attributes to your symbol. You can also select it from the Type it or Browse options in the bottom left-hand corner of the icon menu.ĪutoCAD Electrical toolset expects certain attributes for each symbol type, schematic parent, schematic child, and so on.
You can add your new symbol to the icon menu. New symbols you create are inserted with the AutoCAD Electrical toolset Insert Component or Insert Panel Component commands. Selecting the objects allows the tool to track what standard attributes and wire connection points you already inserted. Each time you re-enter the Symbol Builder tool, select objects from within the Select Symbol/Objects dialog box. The AutoCAD Wblock command writes it to disk.
You can also exit the command and use regular AutoCAD commands to edit or finish the symbol you are creating. You can exit the Symbol Builder command and re-enter it at any time. They break wires upon insertion, and appear in the bill of material and various component and wire connection reports. Symbols created or converted using Symbol Builder are fully compatible with AutoCAD Electrical toolset. You can convert symbols or create custom components on the fly. swap or update), just sit back and let it do its thing.Defines new AutoCAD Electrical toolset component, terminal, and panel layout library symbols. Once you tell it what you want to do (i.e. (You can't purge any object that is still 'in use'.) Only after a block definition has been purged, will ACAD actually go fetch the new, edited block you made.Īnd that's the beauty of the Swap/Update Block does all this for you in one single dialog box. The PURGE command will remove block definitions from a drawing, IF all existing instances have been erased. This is a time-saving and computer-resource saving measure it's faster and uses less processing power than actually going to an external file somewhere and copying the information all over again. Later, when you need to insert that block again, ACAD will use this already-existing copied information, which is called a 'block definition'. To expand slightly on jtoverka's (correct) reply, here's what is happening:Īny time you insert a block for the first time in ACAD-based software, there's something that happens in the background: the software makes a copy of that block and stores it in its internal drawing database. It will replace all existing instances of a block with the new, edited version (or an entirely different block, if that's what you need). AutoCAD Electrical has a special tool for this, Swap/Update Block.
